Tein Saturn Ion S. Tech Springs are probably the most sought after springs in the industry.
In the early days of the tuner culture, there was a coilover suspension kit that was only spoken of in legend and rumors, Tein Suspension. Back then, Tein was only available in Japan and only the die hard tuners who flew to Japan and brought a set back with them were able to add the legendary suspension to their car. With the new millennia though, Tein was finally made widely available to the American public around 2001. In addition, they offered not only the coil over suspension that had made them famous, but also stand alone lowering springs for your 03-07 Saturn Ion that have proven to be the most popular lowering springs on the market.
These Tein Ion springs are the S. Tech type, which are designed to offer a lower, more aggressive drop for better looks and better performance. Sold in the full set of 4.
